Derrick Morgan’s educational process started with headlines and movies. The Titans’ seventh-year linebacker had seen the reports about chronic traumatic encephalopathy (CTE). He had read the study that found the disease in the brains of 87 out of 91 deceased NFL players. He had seen the movie “Concussion” and, of course, he had heard the stories of former players dealing with lingering effects from football injuries.
But Morgan’s research also included the 2013 CNN documentary “Weed” about then-5-year-old Charlotte Figi, whose family turned to cannabis as a last-ditch effort to significantly reduce her epileptic seizures.
